Rumor has it that "Left 4 Dead 3" is currently on the works.

Talks for the new version proliferated after Valve is accordingly searching for a new office next year that will enable them to accomplish all the works that are vital to their upcoming projects.

The move is considered by fans as an indication that a team of game developers is getting ready to focus on the development of a game.

In addition to that, a teaser which includes a tutorial file showing a folder believed to be attributed to the game has surfaced.

The teaser is made up of a series of photos of the tutorial where a folder was being uploaded by Valve artist Tristan Reidford.

The photos were subsequently removed but ValveTime shared a copy of the images, which convinced gamers to think that Valve is indeed working on a new project.

Fans hope that Valve will launch "Left 4 Dead 3" sometime in 2017.
